For their points cost,T4, S4, and a 5+ inv seems like a good deal regardless of the power they randomly generate. If you play them as a statline and ignore the powers, I think I could get a lot of mileage out of these guys.

The "sleeper" craziness of the new Codex: Inquisition is the servo skulls becoming available with no need for usage of "allies" to all Imperial armies. The ability to almost completely negate all scouting and infiltration for 3 points per skull is just crazy talk. Hell if it was 15 points a servo skull it would still be a boon to Marines and Guard and you'd see people running it.

Well the idea is that now there's no need to "ally-in" to get the servo skulls. My understanding now is that you can just bring in an Inquisition model/unit without the need for an ally force org (and the additional costs that come with it, as well as at that point dictating your allies as Inquisition) and then buy the servo skulls through them at the dirt cheap 3 points each. Space Marine players, especially biker armies, would be out of their mind not to bring such an addition to their force org to ensure they keep the mid-field wide open and deny strategic ruins/forests to infiltrators.

To be fair, I'm a Tau player bitching about a Marine/Imperial benefit. It's not like we don't get our own fun freebies. But this really is quite a strategic deal for non-xenos/non-chaos armies.
